The Effects of Quality Assurance Measures on the Overall Performance of Government Secondary Schools’ Construction Projects in Dodoma City.

Abstract

The study focused on assessing effects of quality assurance measures on the overall performance of government secondary schools’ construction projects in Dodoma City, Tanzania. The population comprised 1473 management and staff members, with a sample size 314 respondents. Data were collected using questionnaires and interviews, with qualitative and quantitative data analysed through descriptive and inferential statistics, including binary logistic regression and Chi square. The data were quantitatively analyzed with the help of the computer software Statistical Package for Social Sciences (SPSS) and Stata. It is important to note that before performing the Logistic Regression Model, the 5-point Likert scale data on Project performance were transformed into an index scale using the overall mean scores. Thus, the mean score greater or equal to the overall mean was termed as high-project performance while the score below the overall mean was termed as lower-project performance. The Logistic regression analysis revealed that approximately 60.3% of the overall performance of government secondary schools’ construction projects can be explained by the quality assurance measures alone (Pseudo R squared = 0.603), with a highly significant LR Chi (3) (LR = 138.4, p < 0.001). Based on this logistic regression analysis, adherence to standards and continuous improvement initiatives are statistically significance on project performance., while Inspection frequency shows a statistically insignificant at 0.05 level of significance.
